A beginner project utilising an Arduino and a BME280 sensor capable of giving you 4 environmental readings.

Building a rain sensing alarm with Arduino.

This is an image processing based fire detection and extinguisher system using Arduino and OpenCV.

+ LCD/OLED can be used to measure body temperature or to detect movement... in Celsius and Fahrenheit!

In this tutorial, you will learn how to use a soil moisture sensor. Practical examples are also provided to help you master the code.

In this tutorial, you will learn how to calibrate and use MQ9 gas sensor with an Arduino board.

This little project will show you how to use a soil moisture sensor.

Read data from an absolute orientation sensor without writing any code!

This project will show you how to use temperature and hmidity (DHT11 and DHT22) sensors with an Arduino card.

I found limited documentation on the usage of a color sensor I recently purchased, so here is my attempt to make it more simple.

A standard speaker can be used to detect vibrations and send data to a microcontroller.

This project allows you to draw your own controller to be used with anything. It utilizes capacitive sensing and graphite's conductivity.

Using ultrasonic sensors to measure distance of obstacles, taking into account temperature and humidity that affect the speed of sound.

I've always wondered if there were any real differences between temperature and humidity sensors, especially DHT11 and DHT22.

This system monitors the moisture of soil and waters it by 5v DC motor based water pump when needed.

This project shows tilt sensors and its functions.

This projects detects knock using Arduino UNO and sends notification to Windows 10, Ubuntu.

An IoT device to automatically switch on/off electronic appliances based on the availability of human beings, especially in public services.

MQ2 Sensor is a gas module and it is suitable to detect Hydrogen, LPG, Smoke, CO, and Alcohol. It has high sensitivity and fast response.

Air meter making, a second time! Let's look at temperature and humidity using the DHT 11 module.

Controlling your project, like a Jedi, with the wave of your hand.

The Arduino 9 Axes Motion Shield allows your Arduino to measure movement: orientation, acceleration and magnetic field.
